To the credit of Google, they finally responded to this issue: the next version – Chrome 86 – a new experimental feature was much more economical.
Currently, the activation of each tab is executed at intervals of not more than five seconds. However, some sewn into the browser’s functions are simply not needed if the user isn’t viewing this particular web page. In particular, processes such as validation scroll position, interaction with advertising or creating reports for journals should not be performed if the tab is inactive.
Google recently tested an alpha version of the browser-enabled. In experiment were used 36 background tabs open to random pages and one active, open on about:blank.
Running the browser twice, once with the included timer and one off, Google engineers have found that the laptop battery worked two hours longer – that is, 28 %.
